    /*
      QFontDef comparison is more complicated than just simple
      per-member comparisons.

      When comparing point/pixel sizes, either point or pixelsize
      could be -1.  in This case we have to compare the non negative
      size value.

      This test will fail if the point-sizes differ by 1/2 point or
      more or they do not round to the same value.  We have to do this
      since our API still uses 'int' point-sizes in the API, but store
      deci-point-sizes internally.

      To compare the family members, we need to parse the font names
      and compare the family/foundry strings separately.  This allows
      us to compare e.g. "Helvetica" and "Helvetica [Adobe]" with
      positive results.
